Abstract
Micro controller CPU (Central Processing Unit) having the following function: 1. External switching mechanism of RS232C 2. Control line to switch the 232C lines, ffor example Parallel Input/Output (PIO) (MERITS) Micro controllers, like Z80, has limited number of SIO (serial Input/Ouput) port(RS232C). To increase it, we have to add SIO chips on the board. It causes cost up.
